RTE in a nutshell

RTE is France’s transmission system operator, in charge of an impressive infrastructure: more than 105 000 km of high and ultra-high-voltage lines spanning the whole of France and 50 interconnections with neighbouring European countries.


RTE is renowned for its expertise. It has been operating, maintaining and developing this grid for 20 years, while constantly balancing supply and demand, second by second.

RTE is a public utility which provides all competing power-generation facilities with non-discriminatory access to the grid.

RTE informs the decisions of the public authorities who make energy policy. It also educates the members of the general public, helping them to gain a better understanding of electricity so that they can use it more efficiently.

Playing a central role within the French and European power systems, RTE is a vital economic partner of businesses and regions, a pivotal player in the energy transition and the move towards renewable energy sources, and a firm proponent of Europe-wide electrical solidarity.

Paths of the electricity

Key dates

Establishment of the transmission system operator
A piece of legislation was enacted requiring the establishment of a transmission system operator, separate from the generation utility. That brought an end to the monopoly of EDF who had previously held both mandates.
Birth of RTE
RTE is a limited company and a wholly owned subsidiary of EDF. Its articles of association guarantee its neutrality with regard to all power-generation facilities.
Change in ownership
RTE’s capital was transferred to CTE (Coentreprise de Transport d’Electricité), jointly owned by EDF (50.1%), the Caisse des Dépôts (29.9%) and CNP Assurances (20%).

And what about tomorrow?

RTE, a responsible and committed corporation
As a public utility, RTE’s DNA is imbued with strong values of transparency, respect and sensitivity to the needs of others. On a day-to-day basis, it works hard to reduce its environmental footprint, to enlarge its societal footprint, to protect its workforce, and to foster close ties and constructive dialogue with its customers, its suppliers and the regions across which its power lines run.

The corporate “Impulsion et Vision” project
From the European Union to France’s regions, the ambitions being sought by the energy transition are considerable and will result in profound changes being made to the whole of the electrical landscape. In response to these changes and its customers’ new expectations, RTE has to adapt, prepare itself and reinvent itself in order to play an active role in driving these future changes.

Pylône fougère
RTE discharges its duties as a public utility within the framework of a regulated monopoly. In consideration of this, most of its revenues come from the price it charges for the use of the transmission system, the amount of which is set by France’s Energy Regulatory Commission (CRE). RTE pays close attention to these financial and economic balances in order to be able to fund its investments as well as its grid operation and maintenance activities, whilst continuing to offer a service at the most affordable cost, thereby helping to boost the competitive strength of economic players and to safeguard the public’s purchasing power.
